Title: Heating element for gas room heaters
Inventor: KIEHL HARRY
IPC: F24H3/00
Filed: 1982-01-25
Abstract: The invention relates to a heating element for gas room heaters for connection to an outside wall or for connection to a chimney. The aim of the invention is to eliminate the disadvantages attaching in particular to the heating elements with multiple connection possibilities and to improve the manufacturing prerequisites for the production of heating elements in different embodiments and output levels with stable functional parameters and positively to influence the hygienic environmental conditions in the operation of outside wall gas room heaters. The object of the invention is to design a heating element in the form of a modular system in such a manner that, by using basic and additional components, the different functions, such as connection to outside wall or chimney with single or multiple connection possibilities and different output levels, are developed and thus the manufacture of large production runs with a high degree of mechanisation is made possible. Associated with the division known per se of the heating element into a basic heating element and a secondary heating element is, as the essential feature of the invention, the varying arrangement of combustion-air and waste-gas shafts in association with separately lying guide pipes for combustion air and waste gas for outside wall connection or flow shafts with the possibility of connection of waste gas pipes for chimney connection. <IMAGE>

Patent DE-3215220-A1 (DE)
Title: Hydraulic steering system for the steerable wheels of a motor vehicle axle
Inventor: HIRTSIEFER MICHAEL DIPL ING
IPC: B62D5/12
Filed: 1982-04-23
Abstract: In a hydraulic steering system for the steerable wheels of a motor vehicle axle, the track rod which engages on the steering levers is divided into two halves in order to obtain hydraulically and mechanically balanced steering forces and symmetrically identical and larger locking angles. The track rod components are supported with their inner ends on the housing of a steering cylinder which has a fixed, if appropriate continuous piston rod, along which the cylinder housing moves backwards and forwards in the case of steering actuation. A guide rod which extends parallel to a rail attached to the axle body receives, over the length of the maximum steering cylinder stroke, a holder for the steering cylinder housing in a sliding fashion, by which means a torque support of the steering forces is produced at the level of the track rod coupling on the holder, the piston rod is largely relieved of bending stress and leakage losses in the steering cylinder are reduced. This effect is promoted if the piston rod ends are mounted in each case in a loose bearing and in a fixed bearing constructed as a swivel bearing. For track width adjustment of the axle they do not have to be offset or adjusted.

Patent DE-3216449-A1 (DE)
Title: Drive unit for a motor vehicle with a stepped transmission
Inventor: SCHNEIDER ARTHUR ING GRAD
IPC: F16F1/10
Filed: 1982-05-03
Abstract: In order to avoid the need for a control circuit encompassing the internal combustion engine (1) to influence the speed of the transmission drive shaft (3) of the stepped transmission (4) for clutch-less shifting, a flywheel (5) with variable moment of inertia is arranged between internal combustion engine (1) and transmission drive shaft (3), which flywheel contains a first component (14) fixedly connected to the crankshaft (2), a second component (15) fixedly connected to the transmission drive shaft (3) and spring steel spirals (17, 18) arranged in an annular chamber (16) between the two components, which spirals have a plurality of turns and are fixed by their ends to the first and second flywheel components (14, 15). If the line of force in the transmission (4) is neutralised, the turns of the spring steel spirals (17, 18) move outward, thereby increasing the moment of inertia of the first flywheel component (14) and consequently reducing the speed of the internal combustion engine. At the same time the speed of rotation of the transmission drive shaft (3) is for a brief period increased, as a result of which synchronous points (S1, S2) are produced for the engagement of the next gear in the transmission (4). <IMAGE>
Patent DE-3218688-A1 (DE)
Title: Snap lock having an actuating device
Inventor: RECHMEIER CHRISTIAN
IPC: E05C1/14
Filed: 1982-05-18
Abstract: There are snap locks which are actuated by means of a countersinkable recessed handle, the lever (rocker) of the recessed handle conventionally being mounted by means of a push-in spindle which has to be mounted through a plurality of holes. An improvement has already been made by a construction according to Patent Application P 2836975.7, but in this it is necessary to use, as far as possible, a material for the lever (rocker) which is flexible, and this does not always afford sufficient strength and, in any case, is impossible if metals are used as the material. The object of the invention is to provide a construction which also makes it possible to use rigid material, whilst the other advantages of the said P 2836975.7 are to be preserved. This is achieved in that recesses, through which the spindles can be mounted, are made in the walls of the grooves.
